## How It Works

1. **User fills out form** (either in header or on contact page)
2. **Clicks Submit** → Form submission prevented
3. **Loading overlay appears** → "Sending your enquiry..."
4. **reCAPTCHA validates** → Google scores the submission
5. **AJAX request sent** → Data sent to `ajax-form-handler.php`
6. **Server processes:**
   - Validates all fields
   - Checks reCAPTCHA score
   - Sends email if valid
   - Returns JSON response
7. **Loading overlay hides**
8. **Modal popup shows:**
   - Success: Green checkmark + "Thank you" message + form resets
   - Error: Red exclamation + error message + form stays filled
